This resource is a collection of 6 slightly different see-saw balances that can be used with learners to help them develop the skills to weigh up an argument. The idea is that students will list reasons on both side of an argument (e.g. Should we have Nuclear Power?). They then use this to help make a decision. The scoring column on some sheets allows learners to score each argument out of a maximum of say 3. Add the scores on each side to see which has the stronger argument. This also includes phrases to support a more detailed conclusion. This was inspired by 21st Century Science.
